We use <a href="http://www.pdflib.com/pdflib-gmbh/" rel="nofollow noreferrer">pdflib</a> to create PDF files from our rails apps. It has bindings for PHP, and a ton of other languages.
We use the commmercial version, but they also have a <a href="http://www.pdflib.com/download/pdflib-family/pdflib-lite/" rel="nofollow noreferrer">free/open source version</a> which has some limitations.
Unfortunately, this only allows creation of PDF's.
If you want to open and 'edit' existing files, pdflib do provide <a href="http://www.pdflib.com/products/pdflib-family/pdi/" rel="nofollow noreferrer">a product which does this this</a>, but costs a <a href="https://www.pdflib.com/buy/online-shop/pdflib-pdflib-pdi-pps/" rel="nofollow noreferrer">LOT</a>

Zend Framework can load and edit existing PDF files. I think it supports revisions too.
I use it to create docs in a project, and it works great. Never edited one though.
Check out the doc <a href="https://web.archive.org/web/20120822101532/http://framework.zend.com:80/manual/en/zend.pdf.create.html" rel="nofollow noreferrer">here</a>

blocks|key|1784179|text|如果你采用“填充空白”的方法，你可以在页面上的任意位置精确定位文本。因此，将缺少的文本添加到文档中相对容易(如果不是有点繁琐的话)。例如，使用Zend+Framework：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1784180|<?php
require_once+'Zend/Pdf.php';

$pdf+=+Zend_Pdf::load('blank.pdf');
$page+=+$pdf->pages[0];
$font+=+Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_HELVETICA);
$page->setFont($font,+12);
$page->drawText('Hello+world!',+72,+720);
$pdf->save('zend.pdf');|code-block|syntax|javascript|1784181|如果您试图替换内联内容，比如“占位符字符串”，事情就会变得复杂得多。虽然这在技术上是可行的，但您可能会弄乱页面的布局。|1784182|PDF文档由一组图元绘制操作组成:此处为直线，此处为图像，此处为文本块，等等。它不包含有关这些图元的布局意图的任何信息。|1784183|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

If you are taking a 'fill in the blank' approach, you can precisely position text anywhere you want on the page. So it's relatively easy (if not a bit tedious) to add the missing text to the document. For example with Zend Framework:

<pre><code>&lt;?php
require_once 'Zend/Pdf.php';

$pdf = Zend_Pdf::load('blank.pdf');
$page = $pdf-&gt;pages[0];
$font = Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_HELVETICA);
$page-&gt;setFont($font, 12);
$page-&gt;drawText('Hello world!', 72, 720);
$pdf-&gt;save('zend.pdf');
</code></pre>

If you're trying to replace inline content, such as a "[placeholder string]," it gets much more complicated. While it's technically possible to do, you're likely to mess up the layout of the page.

A PDF document is comprised of a set of primitive drawing operations: line here, image here, text chunk there, etc. It does not contain any information about the layout intent of those primitives.

blocks|key|1569331|text|PHP中的PDF/pdflib扩展文档很稀疏(在bugs.php.net中已经注意到了这一点)-我建议您使用Zend库。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1569332|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The PDF/pdflib extension documentation in PHP is sparse (something that has been noted in bugs.php.net) - I reccommend you use the Zend library.

blocks|key|1784369|text|如果你需要非常简单的PDF，那么Zend或FPDF就可以了。然而，我发现使用它们既困难又令人沮丧。此外，由于API的工作方式，没有好的方法将内容、表示和业务逻辑分开。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1784370|出于这个原因，我使用dompdf，它可以自动将HTML和CSS转换为PDF文档。您可以像布局HTML页面一样设置模板的布局，并使用标准HTML语法。您甚至可以包含一个外部CSS文件。这个库并不完美，非常复杂的标记或css有时会被破坏，但我还没有找到其他同样有效的库。|1784371|entityMap|0|LINK|mutability|MUTABLE|url|http://www.fpdf.org/|1|https://github.com/dompdf/dompdf^0|L|4|0|0|A|6|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

If you need really simple PDFs, then Zend or <a href="http://www.fpdf.org/" rel="noreferrer">FPDF</a> is fine. However I find them difficult and frustrating to work with. Also, because of the way the API works, there's no good way to separate content from presentation from business logic.

For that reason, I use <a href="https://github.com/dompdf/dompdf" rel="noreferrer">dompdf</a>, which automatically converts HTML and CSS to PDF documents. You can lay out a template just as you would for an HTML page and use standard HTML syntax. You can even include an external CSS file. The library isn't perfect and very complex markup or css sometimes gets mangled, but I haven't found anything else that works as well.

blocks|key|1784477|text|我不知道这是否可行，但它的工作原理与zend的pdf库非常相似，但您不需要加载大量额外的代码(zend框架)。它只是扩展了FPDF。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1784478|http://www.setasign.de/products/pdf-php-solutions/fpdi/|offset|length|1784479|在这里，你基本上可以做同样的事情。加载PDF，覆盖它，然后保存为新的PDF。在FPDI中，您基本上是将PDF作为图像插入，因此您可以在其上放置任何您想要的内容。|1784480|再说一次，它使用的是FPDF，所以如果你不想使用它，它就不会工作。|1784481|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|1J|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@$D|S|E|T|1|U]]|A|$]]|$1|F|3|G|5|6|7|V|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|W|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|X|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|C]]]]

Don't know if this is an option, but it would work very similar to Zend's pdf library, but you don't need to load a bunch of extra code (the zend framework). It just extends FPDF.

<a href="http://www.setasign.de/products/pdf-php-solutions/fpdi/" rel="nofollow noreferrer">http://www.setasign.de/products/pdf-php-solutions/fpdi/</a>

Here you can basically do the same thing. Load the PDF, write over top of it, and then save to a new PDF. In FPDI you basically insert the PDF as an image so you can put whatever you want over it.

But again, this uses FPDF, so if you don't want to use that, then it won't work.

Does anyone know of a good method for editing PDFs in PHP? Preferably open-source/zero-license cost methods. :)
I am thinking along the lines of opening a PDF file, replacing text in the PDF and then writing out the modified version of the PDF?

有没有人知道用PHP编辑PDF的好方法？最好是开源/零许可成本的方法。:)我的思路是打开PDF文件，替换PDF中的文本，然后写出修改后的PDF版本？在前端
